USING SIMULATION FOR COMPARING THE RESPONSE OF MATERIALS IN TERMINAL BALLISTICS
Résumé
This paper presents a simulation of a bullet impact on a plate, the materials being assigned to a bilinear isotropic hardening model, with a constant equivalent plastic strain for each involved material. The model takes into account the yield and fracture limits of both involved materials for the bullet and the plate one. The projectile has the dimensions of a 9 mm FMJ (full metal jacket). The model was developed with the help of Ansys 14.5. The authors presented the influence of the properties the plate is made of (steel or aluminium alloy). Also, they established a correlation between the evolution of the theoretical maximum von Mises stresses and the stages taking place during the impact.
